Answer 2

Heya ✋

Let see your answer !!!!

Given that

$surface \: area \: of \: a \: cube \: \\ = 150m ^{2}$
Volume of a cube = ?

Solution

$surface \: of \: cube \: = 6l ^{2} \\ = > 150 = 6l ^{2} \\ = > \frac{150}{6} = l ^{2} \\ = > 25 = l ^{2} \\ = > l = \sqrt{25} \\ = > l = 5m$
$volume \: of \: cube \: = (side) ^{2} \\ = (5) ^{3} \\ = > 125m ^{3}$
Thanks :))))
